Application f led January 29, 1926., Serial No.

This invention relates to spinning, douhling and like machines of theflier type having mechanical dotting mechanism in which it is foundsomewhat diiiicult to prevent the drag washers from being displaced atone time or other during the carrying out of the doliing process. Ourpresent invention consists in the application of means where by Thedisplacement of the washers at all .imes prevented while the same meansaliord facilities for retaining and moving the bob bins during certainparts of the dofing process which we now carry out by the employment oithe novel .devicesdiereinaiter explained.

In order that our said invention may be readily understood, we havehereunto appended sheets of drawings illustrative thereof in which l isa front elevation showing the several parts of the machine in theirrespective positions during the spinning operations.

Fig. 2 is an end elevation of the parts shown by Fig. 1 also in thepositions they occupy as shown by said Fig. 1.

Fig. 3 is a similar end elevation to Fig. 2 but shows certain :of theparts adjusted in their respective positions during one of the firststages of the doifing process.

Fig. 11 is a front elevation of the parts shown by Fig. 10.

Figs. 10 and 11 are drawn to a smaller scale than are Figs. 7, 8 and 9.

A indicates the end frames of the machine, and B the foot-step orsupporting rail for the spindles. All the otherrparts shown by thedrawings, and which are not hereinafter referred to are of the ordinaryand usual formation .and construction.

It may be here observed that the doliing process and many of themovements oi the devices for carrying same into effect to which ourpresent invention relates are well known to those having a knowledge ofthe spinning industry, so that we have hereinafter only referred to sameto such an ex- :tent as would clearly show wherein our .novel devicesCllfiBI "from those previously employed for carrying out the removal ofthe full bobbins (after the spinning operations had proceeded as far :asdesired) on the stopping of the machine and the supplying of emptybobbins to take their place prior to the restarting of the machine.

Further the kind of machinery in which our doffing apparatus has to bemade use of is that known as flier spinning, doubling, twisting and likeframes, wherein the fliers 4* at all times revolve with the spindle 4upon which they are fixed.

In carrying out our invention we employ a receptacle or holder 2 for thedrag washers 3 (see Figs. 7 and 8) on each spindle l of the machine.

This holder 2 is preferably formed of sheet metal by the process ofstamping although we are aware that it may be formed by casting orotherwise.

'The holder 2 has a central opening for the spindle 4 to pass throughwhile it has projections 2 formed on it to span the lifter rail5 uponwhich it is loosely mounted and by which projections it is held againstrota- .tion by said lifter rail. 5.

From the base of the holder '2 we have other projections 2 arranged toextend vertically above same so as to hold orretain the drag washers 3within while said drag washers are arranged to surround the spindles 4:upon which the fliers 4 are fixed. The "ertical projections 2 aresituated laterally the spindle and are formed to have their upper ends aslightly lower than the upper surface b of the drag washer 8 upon whichthe bobbin 6 rests, when mounted upon its spindle 4 while saidprojections 2 are sufficiently far from the .spindle as to be en tirely"clear of the base or flange of the bobbin 6, thus giving the bobbin 6perfect freedom to rest upon the washers without being interfered withby said projections 2 The spaces'between the projections 2 are to affordaccess to the washers 3 in order that any accumulated fluffy or likematter may be readily removed by the attendant.

When using the washer holders 2 constructed as above described wearrange the lifter plate to be slidable lengthwise the machine whileresting upon the upper ends of their lifter rods 7.

This is permitted by slots 5* being made in the lifter plate 5 (see 10)to span the upper ends of the lifter rods 7 while yet being supported bythe flanges 7 on said rods.

When the dofiing has to commence, after the arresting of the machine andthe adjusting of the lifter rail 5 and other parts as above described,the attendant will operate the handle to oscillate the shaft 41 so thatby pinions 42 engaging racks 43 the step rail B carried by said racks,may be lowered in order to remove the foot-step bearings 44 clear of thelower ends of the spindles 4 in the usual manner.

After thus lowering the rail B we then lower the lifter rail 5 so thatit and the drag washers 3 are clear of the lower ends of the spindles 4,the attendant then slides said lifter rail 5 longitudinally by thehandle 5 in order to carry the washer holders 2 (along with the saidlifter rail which is effected by a lateral. flange 2 taking into theopenings in the lifter rail 5 as shown by Fig. 7 so that the verticalprojections 2 on these holders 2 are brought beneath the flanges 6 (seeFig. 11) at the lower ends of the bob- I bins 6 by which means certainportions, of

said flanges will overhang said projections and thus afford spacesbeneath said flanges for the insertion of the holding shoe 8 which maythus be brought into position to support said bobbin 6 upon its spindle4 and permit the lifter plate 5 to be further lowered out of the way ofthe spindles 4 as is shown (see Fig. By this arrangement of the partsdescribed bobbins 6 may on the removal of the shoes 8 be permitted tofall or descend from their respective spindles 4 on to the pegs 9 fixedupon a peg rail 10 arranged to receive them as is shown by Fig.3.

The moving forward of the spindles 4 from their operating positionsshown by Fig. 2 to their advanced positions shown by Fig. 3 is effectedby the supporting rail 11, which has the upper bearings 11 for thespindles 4 mounted upon it, being mounted to oscillate upon its bearingsin well known manner; the said movement of the rail 11 being effected bythe handle device 12 which the attendant actuates to move the well knowntoothed quadrants 13 and 14 arranged in connection with the rail 11.

After the parts have been adjusted as stated the attendant will thenoperate the handle 15 to bring the shoes or bobbin holders 8 from theposition they occupy as shown by Fig. 3 into the rear position shown byFig. 4 so that the bobbins 6 on the spindles 4 are permitted to fall ordescend on to the pegs 9 as is before stated. hen the bobbins have thusdescended on to the pegs 9 he then moves the spindles a short spaceforward by actuating the handle 12 after which the rail 10 upon whichthe pegs 9 are fixed is turned upon its bearings (upon which it ismounted to oscillate) from the position shown in Fig. 3 into theposition shown by -Fig. 4 at which time a rod 20 will have moved bygravity along the curved slots 21 in the brackets 21 which is also fixedupon the rail 10, into the position shown by Fig. 4 and will havecarried with it the threads or yarn 6 extending from the bobbins 6 sothat any of such threads 6 which might have encircled the ends of thespindles 4 as they were being uncoiled from their bobbins 6 (somewhat asis shown by Fig.3) will by the descending movement of the rod 20 becarried beyond the ends of the spindle 4, thus leaving said thread freeto be acted upon as is well known.

The attendant then operates the handle 12 so as to bring the spindles 4into the position shown by Fig. 5 in which said spindles are in perfectalignment with pegs 16 upon which the empty bobbins 6 are situated. Whenthe spindles 4 are thus in alignment with the pegs 16 the attendant thenrevolves the hand wheel 17 which (by well known gearing) raises theracks 18 so that a thread cutter 19 mounted at the upper ends of saidracks 18 will come in contact with the lower ends of the bobbins 6 andraise said bobbins on to the spindles 4 on which the shoes or bobbinholders 8 will again be operated by the handle 15 to cause said holdersto pass beneath the bases of the empty bobbins 16 and retain them on thespindles 4. After this adjustment of the empty bobbins the attendantwill readjust the lifter rail 5 and then will further move back thespindles 4 and the bobbin holders 8 from the position shown in Fig; 3tothe position shown in Fig. 6 this being effected by the usual and wellknown handle devices which are opera-ted in the manner hereinbeforeexplained.

On the parts being readjusted in the positions shown by Fig. 6 theattendant will then operate the handle 40 to readjust the rail B in itsposition'for its foot-step bearings to support the spindles 4. He willthen operate the hand wheel 17 to raise the racks 18 in order to liftthe thread cutter 19 into the po tion "shown by said Figmfiso that onthe machine being started into motion the attendant may slide saidthread cutter in known manner lengthwise the machine to sever thethreads after same have been wound for the desired number 05E turns orcoils around the bobbin 6, by the commence nient oi the spinningoperations.

The form of foot-step bearing 44 which we employ'is produced by a bodymember having an inner member l-i? forced into a central opening madeaxially therein. The inner "member has its upper part of less diameterthan the part below so that an inner annular space '20 is formed at thispart to receive lubricant which will flow over the upper end to enterthe cavity a" where the end of the spindle is supported and where itrotates. The'body'meniber is mounted in an opening made in the step railB and is held against rotation by a screw 45, while by the nut 46 takingover the screwed part of the member 44E, this latter may be adjustedvertically to meet any :of the requirements of the spindle 4..
